Universal Cable: DRAKA U-DQ(ZN)BH 4G OM3 (4xOM3)

A look at the construction of the cable

Key features:

• gel-filled central tube
• reinforced by aramid yarn
• 4 multimode OM3 fibers in tight tube
• LSZH jacket
• suitable for indoor and outdoor use
• thinner and lighter than outdoor cables

DRAKA U-DQ(ZN)BH 4G OM3 is a universal fiber optic cable for indoor and outdoor applications. Multimode OM3 fibers are contained in central gel-filled tube. The gel in the tube is a kind of protective coating for optical fibers, which absorbs mechanical stresses and protects the fibers against environmental factors. The aramid yarn covering the central tube provides additional protection against mechanical damage, including risks posed by rodents.

DRAKA U-DQ(ZN)BH 4G OM3 cable contains 4 multimode fibers (J-Fibre). The color identification of the buffer layers complies with the TIA-EIA-598-A standard. The jacket (sheath) is made of low smoke zero halogen flame retardant material (LSZH).

The multimode fibers used in the cable are OM3 50/125, currently the most popular multimode fibers that can be used for transmission in the I or II transmission window (850/1310 nm). The attenuation (IL) does not exceed 3.5 dB/km in the first transmission window, and 1.5 dB/km in the second transmission window. OM3 standard provides higher data throughput over greater distances than its predecessors. The transmission speed of 10 Gbps is possible at distances up to 550 m, and higher speeds, such as 40 Gbps and 100 Gbps can be reached at 100 meters (OM1 and OM2 standards do not allow for such fast rates).

Universal cables from DRAKA U-DQ(ZN)BHI series are gel-filled fiber optic cables intended for horizontal connections in buildings and outside buildings. Due to the small size and flexibility, the cables are ideal for installation in cable ducts. They are used in modern FTTH and FTTB systems, in server rooms, between buildings. Unlike external cables, universal cables can also be used inside buildings. This eliminates the need to create additional transitions, splices and cable distribution frames at the junction of the external and internal networks. Universal cables can be laid in cable ducts or even directly in trenches in the ground (in places where they are not exposed to direct mechanical damage).
